"It's a big deal. I'm going to be out here every day of the week," said golf fan J.P. Davis.

PGA fever has hit Louisville and many are kicking it off with shopping.

The football field-sized, air conditioned tent holds more than 400,000 items.

"Once you come out here you're going to spend more than I think you want to spend because there's all kinds of really cool shirts, and T-shirts and hats. It's amazing how much stuff they have here," said Davis.

"Golf balls, tees, coasters for your glasses, water bottles, you name it they have it," said golf fan Clarice Rogers.

For now, no purchase is necessary to browse. Officials said that will change soon, though.

"People that don't have a ticket next week, this is their only chance because of course next week you need a ticket. For the people that do have tickets next week, and really want to focus on the golf and watching their favorite players, this gives them a chance to come out and just focus on their shopping experience," said Michael Quirk, senior director of PGA Merchandise.

"I would rather be out watching the golfers while I'm here on Friday, so yeah, I didn't want to have to take the time to come to the store," said Rogers.

For the golfers, it's a chance to get some stuff they can only get at the championship, including items with the PGA and Valhalla logos.

Non-golfers have a wealth of athletic merchandise to choose from, too. And for the football fan, there was University of Kentucky and University of Louisville-themed gear.

"I didn't even come to look for something like that, and end up finding a Louisville shirt and a hat. We got one of each. That's pretty neat, too, a nice touch," said Davis.

Officials said they're expecting between 5,000 and 6,000 people over the next two days.

It's the first time the tournament and store have been at Valhalla since 2000.

"I'm surprised it took them that long to come back but I'm glad they did," said Davis.

The store will reopen to the public Sunday from 10 a.m. until 6 p.m. Parking is free just across the street in the Vahalla Golf Club Lot X.

WLKY and CBS will have third and fourth round coverage of the PGA Championship.
